org.springframework.amqp.rabbit.listener.exception.ListenerExecutionFailedException

[Babasaheb Patil]

Hi,

I'm trying to use simple JSON  object to be passed through Rabbit MQ. 

I converted the JSON object to String and sent and when I received it, I simply converted it back to MongoDB Document/Entity object. In debug mode I can see it nicely got passed through Queue and got consumed and got converted back to Entity/Document Object using JSON parser.

After that, I tried to insert that object in MongoDB then it's failing for below error.

Can someone help me with this error ?

Thanks

Baba

Looks like a problem (NPE) in your listener.

Thank Gary. But I can see that message got consumed as I was able to read message and convert it back to Documet object.

But after mongoopertaions.save command while inserting the document to MongoDb its failing.

Gary, if you have time can we zoom in meeting and take a look at it if you have time ?

Thanks

Baba

No; I can't provide individual support; you are clearly getting a NullPointerException in your code; use a debugger.

Garry, 

As its a Spring Boot and Rabbit MQ application, is it having below issue that you replied someone?

You are creating two separate application contexts:

context = new AnnotationConfigApplicationContext(AMQPPoCReceiverApplication.class);

is not needed.

SpringApplication.run(AMQPPoCReceiverApplication.class, args);

also creates one. You should not create another context in CommandLineRunner.run(). Simply use:

ConfigurableApplicationContext context = SpringApplication.run(AMQPPoCReceiverApplication.class, args);

I bet it's a misconfiguration and not a bug in any of the projects :)

I replied because you implied it was a Spring AMQP issue and the stack trace shows you are using it.

That log does not help without more context.

Since your issue has nothing to do with RabbitMQ, I suggest you move the discussion to Stack Overflow [1] or Gitter [2].

In either case, you must provide much more information, code, logs; and first of all, figure out your NullPointerException.
